  • RETICLE CONTAINER HAVING MAGNETIC PARTICLE CAPTURE
    Publication number: 20230384695
    Abstract: Reticle containers include a cover and a baseplate, with magnetic particle traps included in at least one of the cover or the baseplate. The cover and baseplate each include sealing surfaces, and at least one of the sealing surfaces includes magnetic material that can be attracted by the magnetic particle traps. The sealing surfaces can be selected such that particulate generated by wear at the sealing surfaces is primarily the magnetic material. The magnetic particle traps can further be configured to be cleaned by reduction of the attraction of the particulate matter to the magnetic particle traps.
